Color in latex.

Colortbl and xcolor packages support the color in latex. However, it can be used with the class file "article". It doesn't support the emulateapj class, which is a pity. The reason why I prefer emulateapj class is that the emulateapj has a good-looking table.


Here are some basic examples for the usage of colortbl and xcolor:

colortbl:

\begin{table}[ht]
%\scriptsize
%\rowcolors[\hline]{2}{rgb:red!50,2;green!50,2;blue!0,1}{}
\caption{rxte data for Model phabs(simpl(kerrbb2)) with nH fixed at 0.46e22$\rm cm^{-2}$ (3.0-8.0 keV) }
\centering
\begin{tabular}{c c c c c c>{\columncolor[gray]{.8}} c>{\columncolor[gray]{.5}} c c c c c}
\begin{tabular}{c c c c c c c c c c c c c c}
\hline\hline
\hline\hline
.......
\end{table}

Xcolor:

\begin{table}[ht]
\caption{rxte data for Model phabs(simpl(kerrbb2)) with nH fixed at 0.46e22$\rm cm^{-2}$ (3.0-20.0 keV) }
\centering
\rowcolors[\hline]{2}{rgb:red!50,2;green!50,2;blue!0,1}{}
\begin{tabular}{c c c c c c c c c c c c}
\hline\hline
.........
\end{table}
